There are a variety of levels of raid, and each provides various levels of performance and fault tolerance. RAID 1 is most common because it utilizes mirroring to double the storage capacity. It’s not 100% reliable. It could take hours for the remaining drives to restore the data in the event that the mirror disk fails. RAID 5 is a different option that combines striping with parity to offer good storage and performance. It requires two additional disks for parity, but it provides the most optimal balance between storage and efficiency.
